The function of the Current Transformer and Votage Transformer is to reduce the AC voltage and the large current in proportion to the value that can be directly measured by the instrument, so as to facilitate the direct measurement by the instrument, and at the same time to provide power for relay protection and automatic devices.Power system with high voltage, large current transformer is the power of information transmission to the low voltage, low current measurement of secondary side, measuring instrument and a special transformer relay protection and automatic device, and the secondary system is a system of contact element, one of the primary winding is connected to the electricity grid, secondary winding respectively with measuring instrument, such as protective device connected to each other.The transformer can measure the voltage, current and electric energy of the primary system in coordination with the measuring instrument and measuring device.Together with relay protection and automatic devices, it can constitute electrical protection and automatic control for various faults of the power grid.The performance of the transformer has a direct impact on the accuracy of the measurement and measurement of the power system and the reliability of the operation of the relay protection device.
